摘要：The wor.d is heading towar.s r.newable ener.y, but the two key disputes that stop its well-known adoption ar. the power.pr.duction level and the pr.ce of the pr.duction. Distr.buted gener.tion (DG), and hybr.d systems with batter. backup ar. the solution for.uninter.upted power.supply. It is obtained using the Multi-Objective Genetic Algor.thm (NSGA II). Techno-economic methodology is used in this pr.posed system for.the size optimization. The r.sult is based on the system cost, in or.er.to meet the load r.quir.ments. The effect of tempor.l sampling is optimized using low-r.te tempor.l data. It is compar.d with hybr.d DC micr.gr.d, which has been optimized using high tempor.l r.solution data.

摘要：In this study,a 2kHz Tonpilz pr.jector.was designed using a Ter.enol-D and modeled in *** the pur.ose of modeling studies,it has been deter.ined that a r.diating head mass exhibits better.tr.nsmitting cur.ent r.sponse（TCr. at 136 mm diameter.wher. the r.sonance occur. at 2.4kHz and the peak value of 118 dB r. 1 μPa/A at 1 m occur. at 12 *** bolt at a 46mm distance fr.m the center.of the head mass offer. r.sonance at 2.4kHz,and the peak value of 115.3 dB r. 1 μPa/A at 1m occur. at *** optimized design is fabr.cated and molded with polyur.thane of 3mm *** pr.totype was tested at the Acoustic Test Facility（ATF） of National Institute of Ocean Technology（NIOT） for.its under.ater.*** on the r.sult,the fundamental r.sonance was deter.ined to be 2.18kHz and the peak value of TCr.of 182 dB r. 1 μPa/A at 1m occur. at 14 *** maximum value of the r. was found to be -190 dB r. 1V/μPa at 1m at a fr.quency of 2.1kHz.
